So I am reading MIT’s first year computer science textbook from the early 80s and the foreword is by Alan Perlis, the first recipient of the Turing Award. It is full of the kind of thing I am thinking about when I wonder if computer programmers have always had a quasi-poetic streak.

Every computer program is a model, hatched in the mind, of a real or mental process. These processes, arising from human experience and thought, are huge in number, intricate in detail, and at any time only partially understood. They are modeled to our permanent satisfaction rarely by our computer programs. Thus even though our programs are carefullly handcrafted discrete collections of symbols, mosaics of interlocking functions, they continually evolve: we change them as our perception of the model deepens, enlarges, generalizes until the model ultimately attains a metastable place within still another model with which we struggle. The source of the exhilaration associated with computer programming is the continual unfolding within the mind and on the computer of mechanisms expressed as programs and the explosion of perception they generate. If art interprets our dreams, the computer executes them in the guise of programs!

If anybody can spot the problem or give me hints, that would be much appreciated-- the programmatic widget shows up, but the declarative one doesn't. I get an error saying "Could not load class 'mycompany.widgets.Example".
